摘要： An optical film having high light transmittance and excellent light diffusibility is provided. The optical film comprises a transparent substrate 1 and a light diffusion layer 2 formed on one or both sides of the substrate 1. As the resin 3 of the light diffusion layer 2, an ionizing radiation curable resin is used in an amount of, preferably, not less than 50% of the resin and a small amount of the light diffusive agent is dispersed therein. The optical film exhibits excellent light diffusion effect even though the content of the light diffusive agent is small and also exhibits high light transmittance because of the small content of the light diffusive agent. Accordingly, this optical film is suitable for applications such as a color liquid crystal display which is required to have a sufficient brightness, and in combination with another optical material such as a prism lens.

摘要： Because light diffusing plates constituting backlight units have high moisture absorbency, light diffusing plates cause deformation such as warp, swell and flexure and adversely affect other members such as liquid crystal cells to cause defective images. A backlight unit that does not generate defective images due to such deformation of light diffusing plate is provided. This backlight unit is a backlight unit 1 comprising light sources 13, a light diffusing plate 14 comprising a synthetic resin and disposed on the light sources, and one or more kinds of optical members 15 and 16 for backlight unit disposed on the light diffusing plate, wherein both surfaces of the light diffusing plate 14 shall have an arithmetical mean deviation (Ra) of 0.1 μm or less according to JIS B0601:1994.
